Chris Chris' Tips
T-15 is a grade of cobalt tool steel, which offers the highest hardness of most common high speed steel grades.

This heavy-duty, high-speed steel grade offers maximum cutting-edge endurance and wear resistance due to its high Vanadium content. The Cobalt content additionally lends it high temperature hardness and resistance to tempering.

Make sure you get the correct inserts for your indexable turning tools.

Our chart of indexable inserts shows which inserts to use with each of our indexable tools.We carry both imported tool bits made of M2 high speed steel and American-made tool bits made of T-15 high speed steel from the A. R. Warner Co.

AISI T-15 provides excellent wear resistance and good hot hardness.
